How long does a mobile app take until it is published? — answered by Engineer Saeed Baatiah
A simple app takes four to eight weeks. A mid-sized app with accounts and payments takes three to six months. Always add two to three weeks for store review: the App Store usually takes a day to a week and may reject a first submission on formal grounds, while Google Play is generally faster. Start the developer account paperwork on day one rather than in the final week — business identity verification alone can take days.
